Upgrade your K1 or K1 Max to the latest anti-clogging technology, or replace your K1C hotend with this premium Upgraded K1 Series Hotend Kit. Featuring an integrated bimetallic "Unicorn" nozzle, this aftermarket hotend is engineered to solve the most common K1 extrusion issues while delivering extreme speeds and high-temperature reliability.

🚨 CRITICAL: Check Your Connector Before Buying

Creality updated the toolhead circuit boards over time. You must check your specific machine before ordering to ensure the plugs fit. We know it adds a step, but checking now saves you from a frustrating return later!

How to check in 3 easy steps:

1. Turn off your printer and remove the plastic front fan cover.
2. Look at the small circuit board (Toolhead PCB) where the hotend cables plug in.
3. Choose your variant:
   • 👉 Terminal WITHOUT Buckle: The plugs are completely smooth and slide in without a clip (Typical for older K1 / K1 Max models).
   • 👉 Terminal WITH Buckle: The plugs have a small plastic latch/snap that locks them into place (Typical for K1C and newer K1 / K1 Max models).

Why Upgrade to the "Unicorn" Design?

• Zero Leakage (All-Metal Integrated Design): The heat break and nozzle are crafted as one solid piece. This eliminates the gap where filament usually leaks inside the heating block, and allows for easy, one-handed cold nozzle swaps.
• Banish Heat Creep: The titanium alloy throat drastically reduces upward heat transfer, keeping your cold zone cool and preventing jams. (Tip: For enclosed K1s, open the top/door when printing low-temp filaments like PLA!)
• 600mm/s High-Flow Performance: The enlarged nozzle chamber increases the melt zone by 30%. With a massive max flow rate of 32 mm³/s and a burr-free orifice, you get perfectly smooth extrusion at top speeds.
• Ultra-Fast 360° Heating: The rugged 60W encircling ceramic heater melts plastic uniformly and reaches 200°C in under 40 seconds.
• High-Temperature Durability (300°C): Crafted from copper alloy and hardened steel, this nozzle easily handles abrasive and engineering-grade filaments like Carbon Fiber (PA-CF, PLA-CF), PC, ABS, and TPU.
